[OE-core] [PATCH 1/1] runqemu: replace bashism with working shell idiom

[Peter Seebach]

The =~ operator is not one of my favorites, not just due to portability
issues, but because it's not well known, and a lot of people might
not expect a regex operator.

The canonical shell idiom for this is to use case with alternation
and wildcards.  As a side note, if you are matching anything containing
core-image-sato, you don't need to also check for core-image-sato-sdk.
